UNITED STATES FRANCIS T'VRZICKY AND FRANK J. VODIGKA, OF CHICAGO.ILLINOIS.

DEODORIZER.

Application filed November 22, 1922. Serial No. 602,603.

To all whom it may concern:

Be it known that we, FRANK J. VODICKA and FRANCIS TvnzIoKY, citizens ofthe Republic of Czechoslovakia, residing at Chicage, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Deodorizers, of which the following is a specification.

Our invention relates to what is know-n in the art as deodorizers, andhas for the primary object thereof, the provision of such an articlethat may be advantageously attached to a conventional type of electricfan, or other draft creating means, whereby the air may be completelyand thoroughly saturated with a deodorant, such as perfume or adisinfectant substance.

A further object of our invention resides in the provision of such anarticle that is not only applicable to conventional types of electricfans, but may be as readily applied to radiators of the hot air type, orin fact any place where there is a natural or an artificial draft,whereby there is mixed with the air a suitable deodorant, a stillfurther object of the invention residing in' the provision of such anarticle that is of simple construction, comparatively inexpensive ofmanufacture, and highly useful of purpose.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indi cate similar parts in the several views,and whereinFigure 1- is a front elevational view of a conventional type of electricfan, showing our improved deodorizer applied thereto.

Figure 2 is a side elevational view of the fan and deodorizer shown inFigure 1.

Figure 3 is an enlarged front plan view of our deodorizer per se.

Figure 4 is a side elevational view thereof.

Figure 5 is a rear elevational view of a slightly modified form of theinvention, showing the same as applied to an electric fan provided witha particular type of wire gu rd frame.

igure 6- is a vertical cross sectional View up n e line 66 f F gu e t esame being shown as removed from the fan guard.

Figure 7- is an enlarged perspective view of the absorbent pad per secmployed in connection with the deodorizer, and

Figure 8 is a fragmentary cross sec tional view upon the line 8-8 ofFigure 1.

Referring to the drawings, there is .disclosed an electric fan of aconventional type and embodying the usual supporting standard 1,electric motor 2, fan 3, and usual wire fanguard 4.

In the preferred embodiment of the invention the usual front wire armsof the guard 4 have connected thereto at their free ends andsubstantially centrally of the fan 3, a ring or collar 5, which is flatin cross section as more clearly shown in Figure 8. This ring or collar5 is provided with a central, annular head 6, and the portion of thecollar outwardly of the head 6 is provided with a pair of diametricallydisposed bayonet slots 7. Our deodorizer includes a substantiallyball-shaped casing 8 having a plurality of spaced perforations 9therein. Adjacent the inner end of this ball-shaped casing 8, the sameis provided with an annular bead 10, whereby the inner end of the casing8 defines a sleeve portion 10. Suitably formed at diametrically oppositepoints upon this sleeve portion 10 of the casing 8, are verticallyprojecting pins 11 adapted for engagement within the bayonct slots 7 ofthe ring or collar 5 when this sleeve portion of the casing is receivedwithin the ring or collar 5, as more clearly shown in Figure 4. In viewof the pins 11, and bayonet slots 7, it will be readily appreciated thatthe casing 8 may be attached and detached from the ring or collar 5, atwill.

Disposed within the casing 8, and preferably within-the groove formed bythe head 10 thereon is a wire mesh cover 12 in the form of a disk. Thiswire mesh disk 12 cooperates with the interior of the side wall of thecasing 8 for supporting therein a padding of suitable absorbent material13. It is to be understood that this absorbent disk 13 is to bethoroughly saturated with a deodorant such as perfume or a disinfectant,and when the casing 8 is disposed upon the guard frame 4: of the fan asshown in Figures 1 and 2, it will be readily understood that air forcedforwardly by the fan 3 will pass through and within the casing 8, andthe padding of absorbent material 13 where:

by the deodorant or disinfectant within this material will be thoroughlymixed with the In the modification shown in Figures 5 and 6, the wirefan guard 4 is provided with the usual central wire ring 5, and in thisinstance, we have provided for attacl'nnent upon this ring, a closureplate 14, provided with an annular row of spaced perforations 15 andfurther with a forwardly projecting annular flange 16. This cover 14 hasformed thereon a plurality of spaced, inwardly extending, struck out,spring arm members 17 adapted for springing engagement over the ring 5'of the fan guard 4 for retaining this cover in a rigid position thereon.The flan e 16 of the cover 14 is also provided with iametricallyopposite bayonet slots for receiving the diametrically oppositeprojecting pins 11 on the sleeve 10 of the casing 8 for securing thiscasing to the cover 14.

We have shown and described our invention as being primarily adapted forapplication to an electric fan, but as before set forth, it isnevertheless to be understood that minor changes may be made in theinvention so as to adapt the same for application to other supports suchas hot air radiators, or the like, whereby the air therefrom will passthrough the deodorizor for effectively extracting some of the deodorantfrom the pad 13 for purposes above set forth.

\V hat we claim as new is A deodorizer comprising an annular collar,means provided upon the collar for attaching the same to a fan guard, acasin shaped like a truncated cone detachably connected with the collarand having a screen located in its larger end and spaced from the edgethereof, a disc shaped pad housed within the casing and having one ofits sides bearing against the screen and its edge at the opposite sidebearing against the inner surface of the cone shaped casing whereby theperipheral surface of the pad is spaced from the inner surface of thecasing, the casing being provided with openings between the screen andthe line of contact of the pad with the inner surface thereof saidcasing being also provided with opgnings beyond the outer surface of thepa In testimony whereof we aflix our signatures.
